Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water.

Africa: Lake Chad basin, upper Benue system (Ref. 248, 57129) and Ubangi River drainage (middle Congo River basin) (Ref. 248). Report from Kogon River (Ref. 13331) unconfirmed and questionable (Ref. 248, 57129).
Dimensione / Peso / Età
Maturità: Lm ?  range ? - ? cm
Max length : 19.5 cm TL maschio/sesso non determinato; (Ref. 57129)
